Direct answer
A Google ad copy generator is a tool that writes the text of a Google ad, the headlines and descriptions a responsive search ad needs, inside Google character limits. Adscreator drafts headlines that fit the 30-character cap and descriptions that fit the 90-character cap, gives you enough of each to fill an RSA, and hands you variants to test different angles. For the Display Network it also generates the on-brand banner creative in every standard size. You paste the copy into Google Ads and export the banners yourself, nothing connects to your account.
The problem
Responsive search ads are a character-counting exercise: up to 15 headlines at 30 characters each and 4 descriptions at 90, all distinct, all on message. Writing that many tight, non-repetitive lines by hand is tedious, and it is easy to blow the limit and get an asset rejected. On the Display side you then need banner creative in half a dozen sizes, which is a separate job entirely.
How Adscreator handles it
Adscreator handles both halves of a Google campaign. For search, describe your product or paste its URL and it writes a full set of RSA headlines that fit the 30-character limit and descriptions that fit the 90-character limit, varied enough that Google has real material to test and rotate. For the Display Network it generates on-brand banner images in the standard sizes (300 x 250, 728 x 90, 320 x 50, 160 x 600, and 300 x 600) in the same pass. Everything runs on flat monthly pricing with no credits, and you paste the copy into Google Ads and export the banners yourself. Adscreator never touches your ad account.

questions
Google ad copy generator: the questions people ask.
What are the character limits for Google Ads?
A responsive search ad headline is capped at 30 characters, and each description at 90 characters. You can supply up to 15 headlines and 4 descriptions, and Google mixes them into combinations. Display path fields are 15 characters each. Adscreator writes copy that fits these caps so assets are not rejected, and gives you a full set to fill the ad.
How many headlines do you need for a responsive search ad?
Google lets you add up to 15 headlines and recommends supplying as many strong, distinct ones as you can, since more material gives the system more combinations to test. Aim for at least 8 to 10 genuinely different angles rather than 15 near-duplicates. Adscreator drafts a varied set inside the 30-character limit so you are not writing them one at a time.
Is there an AI tool for Google Ads copy?
Yes. Adscreator writes responsive search ad headlines and descriptions inside Google character limits from a product description or URL, and generates on-brand display banners in every standard size for the Display Network. You get variants to test, then paste the copy into Google Ads and export the banner files yourself. It writes copy and static creative, not video.
How much does a Google ad copy generator cost?
Adscreator is flat monthly: $39 on Starter, or $29 a month billed yearly, with no credits, so you can generate full RSA sets and display banners as often as you test. There is no free plan. Your Google Ads media spend is separate, since Google bills you directly for the clicks your ads earn.
